Aditionally, plumule length (PL) and plumule dry weight (PDW) from 10 normal seedlings were measured; PL was the length (cm) from the base of the stem to the apex of the youngest leaf; and PDW (mg per seedling) was recorded after seedlings were dried in an oven at 75[degrees]C for 72h.

Plumule and radicle length traits both had reducing trend in relation to different levels of drought stress so that with more negative potential the plumule and radicle length from control to -4 bar decreased significantly 66.

Mauseth (1988) presents a longitudinal section of the embryo of a grass species (Panicum maximum) where, similar to the embryos of corn and wheat, all the cells composing the coleorhiza are vacuolated cells whereas the cells of the radicle, plumule and even the coleoptile are meristematic.
